replacing builtins (WAS: Regular Expressions: large amount of or's)

Manlio Perillo wrote:
Python allows to subclass builtin classes but the Python Interpreter
uses builtin types.
As an example keyword arguments are inserted in a dict but I would
like to use an user defined SortedDict.

There are plans to add such a feature in a future version?


Note that it's polite to start a new thread when you change topic.

That said, I don't expect Python will ever let you replace things like
this -- it means that libraries would not be able to depend on
consistent behavior across users. What would happen if I did something
like:

class BrokenDict(dict):
def __getitem__(self, key):
raise TypeError

and then set Python's dict to this dict instead? I would break pretty
much every function that takes a **kwargs argument.
